The Yakima Copperhead Bike Mount easily attaches to virtually any fork with locking Long-Throw Skewer. With great stability and ergonomics with new fork block design, the Copperhead is a rack to gaze at in quiet awe. Mounts equally well to round or square crossbars and fits all popular tires and rims with new wheeltray and wheelstop. Yakima's copperhead is also very wallet friendly, making it an aggressive mount that's easily tamed to your budget!
